Ms Siobhán Barron:

On the cost relating to a universally designed home, there is only anecdotal evidence so far but we will do a cost-benefit analysis and we hope to have further information within the next 12 months. Sustainability is the added value in that housing and it is not just about physical cost and savings in the context of retrofitting. We are doing much work with the agencies dealing with the environment, including the Sustainable Energy Authority of Ireland, on the matter. Much can be advanced in that way.
